CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/800,371, filed on Mar. 15, 2013 and entitled “Music Discovery Using Messages of a Messaging Platform.” U.S. Provisional Patent Application Ser. No. 61/800,371 is incorporated by reference herein, in its entirety.

BACKGROUND

As technology advances in the areas of social networking and collaboration, sharing multimedia content has become easier than ever before. For example, social networks have made it possible for artists to connect with their fans and to promote their work directly to interested users. Users can then share this content, in addition to relevant personal interests (e.g., musical preferences), with other users. Even further, users can connect with other users with similar interests (i.e., by engaging with similar content online). Using ever more ubiquitous mobile devices, users can share their experiences and engage with other users in real-time.

With the advent of low-cost recording and production technologies, music production has also been revolutionized. Artists can produce, share, and promote their music from the comfort of their own homes, and for a fraction of the price of traditional music production. Record labels and studios have also benefited. With viral/social marketing campaigns, music can be promoted far more easily and with far more relevant advertising than television or print media.

In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

In general, embodiments of the invention provide a method and system for identifying music-related data based on message data from a messaging platform. A music request is received from a client. The request can include, for example, associated context data. Data from the messaging platform can then be identified and used, in conjunction with the associated context data, to identify one or more accounts of the messaging platform. A result set including the identified accounts is provided to the client in response to the music request.

In general, embodiments of the invention provide a user interface for presenting music-related content to one or more users, based on message data of a messaging platform. The user interface can present the message-related content based on popularity, popularity trend(s), relationship data from a connection graph, interest data associated with a user account, and/or any number of other information obtained from the messaging platform.

FIG. 1 shows a messaging platform (100) and a client (105) in accordance with one or more embodiments of the invention. As shown in FIG. 1, the messaging platform (100) has multiple components including a music runtime engine (150), a music aggregation module (145), a music repository (148), a frontend module (110), a routing module (125), a graph fanout module (130), a delivery module (135), a message repository (140), a connection graph repository (142), a stream repository (144), and an account repository (146). Various components of the messaging platform (100) can be located on the same device (e.g., a server, mainframe, desktop Personal Computer (PC), laptop, Personal Digital Assistant (PDA), telephone, mobile phone, kiosk, cable box, and any other device) or can be located on separate devices connected by a network (e.g., a local area network (LAN), the Internet, etc.). Those skilled in the art will appreciate that there can be more than one of each separate component running on a device, as well as any combination of these components within a given embodiment of the invention.

In one or more embodiments of the invention, the messaging platform (100) is a platform for facilitating real-time communication between one or more entities. For example, the messaging platform (100) may store millions of accounts of individuals, businesses, and/or other entities (e.g., pseudonym accounts, novelty accounts, etc.). One or more users of each account may use the messaging platform (100) to send messages to other accounts inside and/or outside of the messaging platform (100). In one or more embodiments, a message is a content container. Messages can include text, video, audio, photos, and/or other types of content, in accordance with various embodiments. The messaging platform (100) may be configured to enable users to communicate in “real-time”, i.e., to converse with other users with a minimal delay and to conduct a conversation with one or more other users during simultaneous sessions. In other words, the messaging platform (100) may allow a user to broadcast messages and may display the messages to one or more other users within a reasonable time frame so as to facilitate a live conversation between the users. Recipients of a message may have a predefined graph relationship with an account of the user broadcasting the message. In one or more embodiments of the invention, the user is not an account holder or is not logged in to an account of the messaging platform (100). In this case, the messaging platform (100) may be configured to allow the user to broadcast messages and/or to utilize other functionality of the messaging platform 100 by associating the user with a temporary account or identifier.

For purposes of this disclosure, a music citation can be any citation of an artist, song, album, recording date, and/or other information related to music content. The following are examples of music citations in various different formats:

-   -   Swedish House Mafia (“Don't You Worry Child”)     -   Bruno Mars—Locked Out of Heaven     -   “Requiem For The Indifferent” by Epica     -   David Guetta—She wolf ft Sia

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to identify a set of websites associated with music. The websites can be obtained from a predefined list or can be identified programmatically using a crawler. Examples of websites associated with music can include, but are not limited to, a billboard music website, a music review blog, an emerging artist's web page, a music studio website, a streaming music website, a digital media store, and/or any other website associated with music.

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to use one or more templates to extract music citations from one or more of the websites associated with music. A template can be any sequence, format, or specific string of text usable in identifying one or more music citations (e.g., according to the chosen method of linguistic matching). For example, a template can be defined to identify a commonly used music citation format (e.g., “[Artist]-[Song]”). Any text matching algorithm can be used to identify the music citations, in accordance with various embodiments of the invention. For example, the music aggregation module (145) can be configured to use an n-gram text matching algorithm to identify music citations. The music citations can include, for example, songs by one or more artists. In one or more embodiments, the music aggregation module (145) is configured to identify a ranking of one or more music citations on the website and to associate the ranking with the music citation in the music repository (148).

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to present the music citations extracted from one or more websites to a human editor for approval and/or modification. The music aggregation module (145) can be configured to receive corrections and/or other modifications to the music citations from the human editor. The human editor may add, remove, and/or modify one or more music citations using a user interface (not shown) of the music aggregation module (145).

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to store an aggregate song list and/or an aggregate artist list in the music repository (148).

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to define one or more templates for identifying messages including music-related content. For example, a template can be defined to identify music citations in one or more messages based on a commonly used hashtag or other keyword (e.g., “# NP”, “nowplaying”, etc.). In another example, a template can be defined to identify a commonly used music citation format among messages of the messaging platform (100) (e.g., “[Artist]-[Song]”).

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to identify a set of messages posted to the messaging platform (100) that include music-related content. Examples of music-related content can include, but are not limited to, a message including a uniform resource locator (URL) of a song hosted by a third-party website, a URL of an artist account of the messaging platform (100), a music citation including a song (e.g., “Lana Del Ray—American”), a message including a comment/review of a song/album/comment of an artist account, a message including a positive/neutral/negative sentiment towards music content, and/or any other content directly or indirectly associated with music. The music aggregation module (145) can be configured to identify music-related content by using any method of linguistic matching, in accordance with various embodiments of the invention. The music aggregation module (145) can be configured to use one or more templates for identifying messages including music-related data. For example, the music aggregation module (145) can be configured to use an n-gram text matching algorithm to identify messages including music-related content. In one or more embodiments, the music aggregation module (145) can be configured to identify the messages including the music-related content in the message repository (140). Alternatively, in one or more embodiments, the music aggregation module (145) can be configured to analyze messages for music-related content as they are ingested by the routing module (125) and to annotate the messages with metadata attributes prior to the messages being stored in the message repository (140).

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to match the identified music citations to the aggregate song list and/or the aggregate artist list. The music aggregation module (145) can be configured to compare one or more songs identified within messages to songs in the aggregate song list. A counter can be maintained for each song in the aggregate song list indicating a number of messages referencing the song within one or more predefined time periods. A counter can also be maintained for each artist in the aggregate artist list indicating a number of messages referencing the artist within one or more predefined time periods. Other attributes of the messages can also be associated with the relevant songs and/or artists in the music repository (148). The music aggregation module (145) can perform a periodic (e.g., daily) analysis of messages posted to the messaging platform (100) or can be configured to perform the analysis on demand as messages are ingested for posting to the messaging platform (100).

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to calculate scores for one or more songs from the aggregate song list based on messages of the messaging platform (100). For example, each score can be calculated based on messages containing music citations referencing a given song in the aggregate song list. The music aggregation module (145) can be configured to score the songs according to a predefined scoring algorithm. The scoring algorithm can require scoring of each unique song based on any number of criteria. Criteria for scoring a song can include, but are not limited to, number of references from messages of the messaging platform (e.g., within a predefined time period), relative (e.g., %) increase in references from messages of the messaging platform within a predefined time period, average engagement with messages referencing the song within a predefined time period, average number of plays per predefined time period (e.g., day, hour, minute), average number of messages referencing the song and including a positive sentiment, and any other input usable in ranking a song. For example, the following scoring algorithm, or a variant thereof, can be used to calculate one or more scores: Score=P*T, where P equals the total number of plays of the song over the past week, and where T equals the trend coefficient of the song. In this example, the trend coefficient is a percentage rate of change in number of plays of the song within the last hour. Subsequent to scoring the songs, the music aggregation module (145) can be configured to order the songs by their corresponding scores in order to generate a ranked list of songs.

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to select the highest scoring songs for inclusion in a ranked list of songs. For example, depending on the scoring criteria used, one or more trending music citations can be included in a top 100 popular music list. Other attributes of the songs and/or artists can be used to generate the ranked list. For example, the music aggregation module (145) can be configured to create multiple lists, each corresponding to a musical genre or other attribute (e.g., “top 10 rock songs”).

In one or more embodiments of the invention, the music aggregation module (145) is configured to include only one song per artist in each ranked list, in order to prevent a single artist from monopolizing the list. Furthermore, in one or more embodiments of the invention, songs that were release prior to a predefined time window (e.g., 1 year) are excluded from the ranked list, regardless of their popularity or score.

Similarly, in one or more embodiments of the invention, the music aggregation module (145) includes functionality to select artist accounts for inclusion in a ranked list of artists. The ranked lists of artists and/or songs can be modified by the music aggregation module (145) based on a credibility rating of the corresponding artist account, an engagement rating of messages of the artist account, a number of followers of the artist account, and/or any other criteria, in accordance with various embodiments.

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to generate one or more top emerging lists. Examples of the top emerging list can include a top emerging songs list and a top emerging artists list. The music aggregation module (145) can be configured to generate one or more top emerging lists by excluding songs and/or artists identified in an aggregate song list and/or aggregate artist list. Thus, for example, the music aggregation module (145) can be configured to generate a ranked list of songs based on each song's popularity. The music aggregation module (145) can then remove songs identified in music citations of a billboard top 100 list of songs, a digital media store, or any website identifying mainstream or popular music. In this way, popular music that is not yet identified by mainstream sources can be identified in the emerging songs list. In one or more embodiments of the invention, the music aggregation module (145) includes functionality to exclude songs and/or artists associated with an artist account that has a number of connections in the connection graph which exceed a predefined number. For example, the music aggregation module (145) can be configured to exclude songs from artists having greater than 50,000 followers of their artist account in the messaging platform (100). Similarly, the emerging artists list can be generated by excluding artists cited in mainstream websites and/or having greater than a predefined number of connections.

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to store one or more ranked lists in the music repository (148). The ranked lists can be periodically or asynchronously updated by a background process of the music aggregation module (145), in accordance with various embodiments of the invention.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to obtain a request for account recommendations from one or more clients (e.g., client (105)). The request can be for any type of music-related accounts. For example, the music runtime engine (150) can be configured to request a ranked list of top popular soul artist accounts, top emerging rap artist accounts, top emerging jazz artist accounts, and etc.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to identify context data associated with the request. Examples of context data can include, but are not limited to, an identifier of an originating account/message/website of a request (e.g., a request for account recommendations), an identifier of an originating application or hardware device of a request, an identifier of one or more recently played songs of an originating account or connected accounts having a graph relationship with the originating account, a type of request (e.g., top rock, emerging reggae, trending rap, etc.), and/or any other context sensitive data usable in identifying music-related content.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to select, based on the context data and data from the messaging platform (100), a set of accounts of the messaging platform (100) for inclusion in a result set. For example, the music runtime engine (150) can be configured to identify accounts by matching an originating account of a user to one or more artist accounts in a ranked list of artists. In this example, the music runtime engine (150) is configured to use a request type of the request (e.g., trending country music) to identify a relevant ranked list of artists (e.g., top trending country artists) and to select the set of accounts from the ranked list. The music runtime engine (150) can also be configured to perform a dynamic ranking of the artists in the ranked list based on the provided context data. Thus, for example, the rankings in the ranked list can be modified based on one or more interests, topics, keywords, and/or attributes of the user account provided as context data. Thus, if a user account has graph relationships with primarily female artists, the scores of female artists in the ranked list can be boosted by a predefined amount. In another example, demographic information of a user provided as context data can be matched to demographic information of the artist accounts in order to modify the scores and rankings in the ranked list. In one or more embodiments, although the ranked list is not modified, the rankings can be dynamically modified by the music runtime engine (150) for a particular request.

In one or more embodiments of the invention, the connection graph repository (142) is configured to store one or more connection graphs. FIG. 2 shows an example depiction of a connection graph (299) in accordance with one or more embodiments of the invention. As shown in FIG. 2, the connection graph (299) has multiple components including nodes representing accounts of the messaging platform (100) (i.e., Account A (200), Account B (202), Account C (204), Account D (206), Account E (208), Account F (210), Account G (212)) and edges connecting the various nodes.

The connection graph (299) is a data structure representing relationships (i.e., connections) between one or more accounts. The connection graph (299) represents accounts as nodes and relationships as edges connecting one or more nodes. A relationship may refer to any association between the accounts (e.g., following, friending, subscribing, tracking, liking, tagging, and/or etc.). The edges of the connection graph (299) may be directed and/or undirected based on the type of relationship, in accordance with various embodiments of the invention.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to identify a set of artist accounts of the messaging platform (100) having a graph relationship with the context account. In one example, the context account is an account of a user making the request. In another example, the context account is an account or authoring account of a message from which a link was selected resulting in the request. The set of artist accounts can be accounts having any type of direct or indirect graph connection to the context account. For example, the set of artist accounts can be accounts followed by the context account, accounts subscribed to by the context account, accounts friends with the context account, accounts liked by the context account, and/or accounts having any other type of connection with the context account.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to identify a ranked list of songs, each associated with an artist account of the messaging platform (100).

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to identify, for each of the associated artist accounts, a bucket of related artist accounts of the messaging platform (100). For purposes of this analysis, each bucket can also include the associated artist account. Thus, for example, the music runtime engine (150) can be configured to fetch 20 related artist accounts similar to an associated account and to construct a bucket to store identifiers of the 20 related artist accounts and the associated account. The related artist accounts can be identified based on attribute matching and/or relevance analysis performed on the associated account and a corpus of artist accounts (in order to identify similar accounts).

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to calculate, for each of the buckets, a score depicting a relevance of the artist accounts of the bucket to the set of artist accounts having the graph relationship with the context account. For example, a Jaccard index can be calculated for the two sets of accounts (i.e., the artist accounts of the bucket and the artist accounts having the graph relationship) using the following formula, or a variant thereof:

Score=|A∩B|/|A∪B|, where A is the set of artist accounts identified by the bucket, and where B is the set of artist accounts having the graph relationship.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to select, for each of at least a subset of the buckets, a number of the related accounts proportional to the score of the bucket. Thus, for example, if a first bucket has a score of 1.2, and a second bucket has a score of 2.4, twice as many accounts are selected from the second bucket. The total number of selected accounts can be any predefined number. The music runtime engine (150) can be configured to perform the selection of the accounts of each bucket randomly, or according to a predefined selection algorithm. The music runtime engine (150) can be configured to include the selected accounts in a result set. In one example, five buckets represented by the characters A, B, C, D, and E are scored as follows: A=2, B=4, C=8, D=4, and E=2. Each bucket includes identifiers of 10 artist accounts. In this example, 10 artist accounts are to be selected from the various buckets. First, the music runtime engine (150) calculates a total of all the scores as 2+4+8+4+2=20. Next, the music runtime engine (150) calculates a number of accounts to be selected from a given bucket X as follows: Nx=(Sx/B)*R, where Nx is the number of accounts to be selected for bucket X, where Sx is the score of the bucket, where B is a summation of all bucket scores, and where R is the number of requested accounts. Thus, the number of accounts selected from each of the buckets in the current example are as follows: Na=(2/20)*10=1 Nb=(4/20)*10=2 Nc=(8/20)*10=4 Nd=(4/20)*10=2 Ne=(2/20)*10=1

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to select the artist accounts from each bucket randomly and to include the selected artist accounts in a result set. In one or more embodiments of the invention, the music runtime engine (150) can be configured to add a promoted artist account to the result set. The music runtime engine (150) can then be configured to provide the result set to the client in response to the request. The promoted artist account can then be displayed by the client (105) with an indication that the account is promoted. In one or more embodiments of the invention, the messaging platform (100) includes functionality to provide self-service advertising to one or more artists by way of a user interface accessible via their artist account. The messaging platform (100) can receive a request to promote the artist account or a song by the artist in exchange for payment. The messaging platform can then insert the promoted account or the promoted song in one or more result sets sent to clients for display to users.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to obtain a song request from a client. The song request can include or be associated with any amount of context data.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to select a set of songs for inclusion in a result set. In one or more embodiments, the songs are selected from a ranked list of songs and can be pruned or re-ranked based on context data associated with the request. For example, songs identified on billboard websites can be removed for an emerging song request. The music runtime engine (150) can be configured to calculate a score for each song based on context data (e.g., musical genres, preferences, followed accounts of a user account, etc.) as well as aggregate data from the messaging platform (100). For example, the music runtime engine (150) can be configured to increase the scores of trending, popular (e.g., high number of plays, shares, comments), and/or highly rated songs. Furthermore, in another example, the music runtime engine (150) can be configured to decrease the scores of songs posted primarily by spam accounts, unpopular songs, and/or lowly rated songs. After scoring the songs, the music runtime engine (150) is configured to select a predefined number of the highest scored songs for inclusion in a result set. In one or more embodiments of the invention, the music runtime engine (150) includes functionality to insert one or more promoted songs into the result set (e.g., at a top of a list of songs). The client (105) can then display the promoted songs with an indication that they are promoted by an artist account.

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to calculate and/or obtain an engagement value associated with a set of messages. The messages can correspond to a particular song or artist in a ranked list, for example. An engagement value is any representation of user engagement with one or more messages posted to the messaging platform (100). Examples of an engagement value can include, but are not limited to, an average number of message rebroadcasts, an average number of favorites, an average number of likes, and an average number of replies, an average number of views, an average number of clicks, and any other measure of engagement with a message.

In one or more embodiments of the invention, the music aggregation module (145) includes functionality to modify or calculate the score of a song or artist based on the engagement value. The engagement value can first be compared with a threshold value (e.g., an expected value). Based on this comparison, the music runtime engine (150) can be configured to modify the score of the message/artist. For example, the engagement value can be included as an input to the scoring algorithm in order to weight the score positively based on higher than expected engagement or to weight the score negatively based on lower than expected engagement. In one or more embodiments, the engagement value is only included as an input to the scoring function if the minimum/maximum threshold value is surpassed.

In one or more embodiments of the invention, the music runtime engine (150) includes functionality to provide the result set to the client in response to the request. Examples of the client can include a mobile application executing on a mobile device, a web browser executing on a laptop computer, a web server hosting content to one or more users, and/or any other software application executing on one or more hardware devices.

In one or more embodiments of the invention, the client (105) includes functionality to display a user interface associated with a selected artist account. For example, the client (105) can be configured to display a profile page of an artist account concurrently with one or more accounts having a graph relationship with the artist account (e.g., accounts followed by the artist).

In one or more embodiments of the invention, the client (105) includes functionality to display a user interface for audio and/or video playback (i.e., a play) of music-related content. FIG. 7 depicts an example of a user interface for audio and video playback. In the example of FIG. 7, a client application displays an audio control widget (playback interface 705) overlaid onto a web page displaying multiple songs. The audio control widget includes a circular progress indicator (710). The circular progress indicator (710) can include a circular progress bar wrapped around a play button and initially (before initiating playback) displayed as a solid color. The circular progress bar then populates with a second color in proportion to the amount of the song which has currently been played. The circular progress bar can be populated in discrete chunks of varying size, in accordance with various embodiments of the invention.

In one or more embodiments of the invention, the client (105) includes functionality to display a user interface (UI) including a grid of UI elements, each corresponding to a song. FIG. 8 shows an example of a UI including such a grid. The client (105) can be configured to select songs for inclusion in the grid according to a request type (e.g., popular, emerging, suggested, # NowPlaying, etc.) selected by a user. FIG. 9 shows an example of a user interface including a menu of selectable UI elements (900-920).

The context data can be matched to attributes of the accounts or otherwise used as a signal for identifying the accounts based on attributes or engagements of the accounts. A result set of accounts is then provided for the client in response to the request for account recommendations (Step 515).

Referring to FIGS. 6A and 6B, in one or more embodiments, a request for account recommendations is received (Step 600) and a context account identified (Step 605). The context account can be, for example, a user account of the messaging platform for which the recommendations are requested. A set of artist accounts having a graph relationship with the context account is then identified (Step 610). The artist accounts can be selected from among all accounts of the messaging platform, or a subset of accounts having one or more predefined characteristics/attributes. A predefined list of artist citations is then identified (Step 615), each authored by or otherwise associated with a verified account of the messaging platform.

Referring to FIG. 6B, a bucket is identified for each of the verified artist accounts (Step 620). Each bucket identifies one or more bucket accounts including the verified artist account and any number of related artist accounts. For each of the buckets, a score is calculated depicting a relationship between the bucket accounts and the set of associated artist accounts (Step 625). For at least a subset of the buckets (or, optionally, all of the buckets), a number of the bucket's accounts proportional to (or otherwise correlated with) the score of the bucket are selected (Step 630). Thus, if a bucket has a higher score, a larger number of that bucket's accounts may be selected. The bucket accounts may be selected based on any number of criteria for selecting top accounts from within a given bucket, in accordance with various embodiments. The selected bucket accounts from any number of buckets may then be provided for the client in response to the request for account recommendations (Step 635).
